Great looking fish. Do you know how big they are?
Mr. Sachs; Great indeed. 3 inches/75mm is not uncommon in the aquarium (2 inches in the wild.) I have kept the fish on 2 occasions, both an absolute delight. IMO they
can grow a
little larger (fatter) especially where there is copious live food. Perhaps even 3 1/2 inches (the last jammy I owned would regularly hold his own (and was very similar in size) to an adult (4 inch) Premnas biaculeatus (maroon clown).
Nick Dakin's "Book Of The Marine Aquarium" (ISBN 0 86101 640 8) fine description;
"P. hexataenia has many of the attributes of an ideal aquarium fish: it rarely bothers invertebrates or other fish (as long as they are not of its own kind, or similar), it is colourful, easily fed, interesting in its activities and generally very inexpensive. This disease resistant fish can be heartily recommended to any newcomer to the hobby."
The only thing I'm concerned about is the striping. If the stripes are too close together, it will create "buzzing" on the screen. This has been a major factor in choosing the fish I can do.
Oh for sure. It would be a real shame, such a colourful active (never still) fish, too.
